SOAP message testing - PeopleSoft Inbound web service

Hi Team,

We are trying to test Inbound Web service for the service operation AP_DCM_GET_SUPPLIER.

1. Generated SOAP message Template
2. Tested successfully using SOAP tested from PeopleSoft

Above steps works fine.

When the same SOAP message is tested via Postman application i get the below response stating External operation name is required.

<?xml version="1.0" ?>

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">

  <SOAP-ENV:Body>

    <SOAP-ENV:Fault>

      <faultcode>SOAP-ENV:Client</faultcode>

      <faultstring>IBRequest:getInfoXMLString(). ExternalOperationName is a required field.</faultstring>

      <detail>

        <IBResponse type="error" xmlns="">

          <DefaultTitle>Integration Broker Response</DefaultTitle>

          <StatusCode>20</StatusCode>

          <MessageID>10403</MessageID>

          <DefaultMessage>

            <![CDATA[]]>

          </DefaultMessage>
